Flutter began as a startup and later was obtained by Google. Today, it’s a free & open-source project and a software development kit (SDK) which leverages Dart (a programming language novel to Flutter) for cross-platform application development. It uses the Skia graphics library (a graphics engine) to render the components.
Apart from rapid and simpler code composing, Flutter likewise gives incredible parts to cause the applications to have a more local-like feel and, subsequently, a better client experience.
Read on to learn about flutter pros and cons so that you can find out whether you should use it for mobile app development or not.
Pros & Cons of Using Flutter for Mobile App Development
As with any technology, there are certain benefits and drawbacks to utilizing flutter for app development. This article will go over central issues, both positive and negative, on Flutter to give you a superior comprehension of when it will be valuable.
Advantages of Flutter App Development
Some of the benefits of using flutter instead of native app development include:
1) Easy Cross-Platform App
At the point when you have the equivalent codebase for iOS, Android, and web application refreshes are more smoothed out. Backend refreshes are likewise done once per update. This diminishes the gamble of conceivable synchronization issues when there are isolated groups of developers answerable for every stage (like in local turn of events).
2) Good App Performance
Flutter could not as yet be on par execution-wise with locally built applications, essentially not in each situation. Be that as it may, applications created in Flutter are as yet responsive and fast. Companies, for example, Tencent or Square, have a lot of clients to please with the encounters their clients get inside the applications. In the event that presentation was an issue, prestigious brands would exclude Flutter in their tech stacks.
In any case, there are strings on Reddit or Stack Overflow where developers are inquiring as to why their Flutter applications are slow. The justification for why some Flutter applications are slow as a rule has nothing to do with Flutter itself.
Truth be told, terrible showing most frequently comes from the absence of abilities and adequate information on Dart and cross-stage development. If you follow ideal practices in Flutter development and improvement, you’ll fabricate quick applications. The documentation for Flutter has a full segment with suggested prescribed procedures that assist with keeping Flutter applications performant.
3) Minimal Code
At the point when you have one codebase that abilities apps that sudden spike in demand for various platforms, how much code you need to compose using text editors & IDEs and afterward keep up with drops considerably. It’s not to say that you will not need to make platform-explicit changes in the code, yet how much code will be not placed near discrete codebases for iOS and Android as found in the native turn of events.
4) Less Testing
At the point when there’s less code to work with, there’s less trying expected to push out every cycle of Flutter-based apps. In a native turn of events, when you have a different codebase for iOS and Android, each new arrival of the application must be tried for both platforms. In Flutter, you can think of one test and run it across all platforms your Flutter chips away at (e.g., iOS, Android, and work area).
5) Rapid Time-to-Market
The thought behind Flutter is to augment code reuse across platforms. And keeping in mind that you can’t anticipate decreasing improvement time considerably, Flutter allows you to shave off a critical piece of that time.
With Flutter, most of the codebase will be no different for all the platforms. When you need to approve your thought rapidly, get financial backers, or just catch a client base, cross-platform arrangements, for example, Flutter SDK, will be an extraordinary decision for application improvement.
6) Convenient Ready-made UI Elements
Flutter provides engineers with an entire assortment of UI components that further accelerate creation. While instant UI parts could influence marking potential open doors, Flutter likewise lets devs redo every part with platform-explicit tweaks. Flutter’s motor makes the UI components render with high FPS that outcomes in a positive client experience.
Disadvantages of Flutter App Development
Here are the cons of using flutter for app development for your next project:
1) Native Development Skills
While that is not really a disadvantage, when you want native usefulness, you’ll have to foster native extensions to execute that usefulness into a particular platform. The scaffold must be written in a native programming language of that platform (e.g., Kotlin/Java for Android and Swift/Objective-C for iOS).
2) Libraries Are Growing but Not Mature
Flutter’s archive is continually developing; nonetheless, the tooling isn’t yet all around as experienced as, for instance, React Native’s. Because there are similarly fewer modules in Flutter, a portion of the functionalities must be provided by open-source modules made by the Flutter people group.
Another downside is that Flutter will, in general, be leaned toward by engineers with a native Android foundation, which influences the quality and usefulness of iOS libraries for Flutter.
So when your application needs exceptionally unambiguous usefulness, it can turn out that there’s no outsider library accessible to help it. Additionally, libraries that truly do uphold it very well may be of inferior quality or, at this point, not kept up with. All things considered, you’ll need to compose the module yourself.
For instance, in one of our tasks, Flutter’s membership library didn’t have the choice to download the finish of the membership date important to approve a client’s honors; we needed to compose the component natively for iOS.
3) Issues with Animations
At the point when you follow Flutter’s accepted procedures during improvement, you can expect great execution results. Nonetheless, there’s one execution issue that has been getting a ton of inclusion as of late.
Developers have observed that in certain occurrences, liveliness is jumpy at first render in Flutter applications (iOS and Android both). This data is legitimate as of April 2021. We’ll refresh the substance the second we discover that Flutter has settled the issue.
4) Limited Libraries
While Flutter has a growing ecosystem of libraries, it may not match the extensive range of well-established frameworks. This could lead to potential limitations for certain functionalities, especially for niche or domain-specific requirements. Developers might need to resort to custom implementations or invest additional effort in finding suitable alternatives.
However, as the framework gains popularity, more libraries and community contributions are likely to address this limitation over time, improving the overall flexibility and feature set of Flutter. Follow the best development practices for this framework and you will see how it shines for you.
5) Steeper Learning Curve
For developers with no prior experience in Dart programming language or Flutter, there might be a steeper learning curve while trying to grasp the intricacies of the framework, potentially leading to slower development progress. This initial learning phase could require extra time and effort to familiarize themselves with the syntax, concepts, and Flutter’s unique development approach.
6) Platform-Specific Bugs
Due to Flutter’s cross-platform nature, it is possible to encounter platform-specific bugs that require meticulous identification and resolution. While the framework aims to provide a seamless experience across platforms, variations in underlying operating systems and devices can lead to unexpected issues, requiring significant bug-fixing time. Addressing these bugs demands additional effort from developers to ensure consistent performance and user experience
7) Limited Support for Older Devices
While Flutter boasts excellent cross-platform compatibility, it may encounter performance issues on certain older devices that lack the necessary hardware capabilities or software support. This could potentially impact the target audience, limiting app accessibility and user experience for users relying on older smartphones or devices.
8) Continuous Updates
Frequent updates in Flutter, driven by its dynamic ecosystem, can sometimes lead to compatibility issues with existing codebases. As the framework evolves rapidly, developers may face challenges in ensuring their apps remain compatible with the latest versions. This could necessitate extra maintenance efforts to address potential bugs and refactor code. This can lead to development issues, slowing down the time-to-market of a particular product.
